This version appeared in all the sources except those of Cornelis Danckerts
and Matthaeus Seutter. Short St George's cross impaled with red swallow-tail
bearing the three yellow lions of England on a white bordered red shield in its
centre. This flag is drawn ignoring the fold in the flag.David Prothero, 21 November 2005

In its October 1949 edition, Mariner's Mirror, Journal of the Society for
Nautical Research, published a letter (page 347) from Hilary Mead, author of
'Sea Flags', asking for information about the "Flag of the English People". The
flag has appeared in a number of continental publications, but apparently, not
in any British ones. Replies were printed in April 1950 (page 164), and added
more examples, all of which are listed below. It was suggested that the flag was
a "processional route" type flag, put up perhaps for the coronation of William
and Mary in 1689. This could explain why it was recorded by foreigner publishers
who would have assumed that it was a genuine flag, but ignored by English
publishers who knew(?) that it was merely a decoration.

Another correspondent wrote that a somewhat similar flag was shown in Visscher's
etching of the ship "White Bear" which was built in 1564. St George canton,
three leopards in pale in the fly and letters ER below the canton. The etching
was reproduced in Keble Chatterton's 'Old Ship Prints' page 62-3.

Another variant was depicted in flag chart created by the Dutch cartographer
Pieter Schenk in 1711, which was published in the atlas by Guillaume Delisle of
France in 1730 (reissued in 1739 as the "Nouvel atlas" by Covens & Mortier of
Amsterdam). [This chart is actually mentioned in the October 1949 edition of
Mariner's Mirror - see the page cited above.] Unlike the other variants, this
one is rectangular. The shield of arms of England is bordered white and set
off-center on red field, near short St George's cross at the hoist. Source:
